Morse Messenger

Encode and decode messages in Morse code using LED flashes

Watch the circuit build itself: components drop in, wires connect, and the output comes alive.

Components

Everything you need for this project.

1x Red LED

220Ω

1x 220Ω resistor

2N2222

1x 2N2222A transistor

1KΩ

1x 1KΩ resistor

1x Push button

5x jumper wires

How It Works

Encoding and decoding information, timing precision, serial communication concepts, and the history of electronic communication.

InputText message input
ProcessingESP32-S3 encodes text to Morse dots/dashes
OutputLED flashes Morse code

What You Build

LED driven by transistor on D1, button input on D2. Type a message on the display, watch it flash in Morse code.

African Context

Morse code was the backbone of early African telecommunications. Understanding encoding/decoding is fundamental to modern digital communication and networking.

What You'll See

Display shows the message and current letter. LED flashes dots and dashes in real-time Morse code pattern.
